Justin Timberlake and Jessica Biel took over hosting duties from their friend, Leonardo DiCaprio, for a Hillary Clinton fundraiser in Los Angeles on Tuesday, where the Democratic presidential nominee posed for several photobooth snaps with the celebrity couple.

"Look who came over for lunch... ? #imwithher," Biel wrote on Instagram.

A Clinton aide tells ET that during the event, she continued to touch on her message of working together, while also arguing that her opponent, Donald Trump, has "shown that he is temperamentally unfit and unqualified to be president."
